Securing the necks to door-knobs



UNITED STATES PATnNT THOMAS KENNEDY, OF BRANFORD, CONNECTICUT.

v. SECURING THE NECKS TO DOOPrKNOBS.

Specication forming part of Letters Patent No. L155,836. dated January10, 1865'.

To LZZ whom it may concern: Y

Be it known that LTHOMAs KENNEDY, of Branford, in the county of NewHaven and State ci" Connecticut, have invented a new and usefulImprovement in Securing the Neck to Knobs; and I do hereby declare thefollowing to be a full, clear, and exact description of the same whentaken in connection with the accompanying drawings and the letters otreference marked thereon, and which said drawings constitute part ofthis specification, a'td represent, in-

Figure 1, a side view of a knob and neck complete; Fig. 2, a centralsection of thesame;

and Figs. 3 and et illustrate the construction,

of the two parts.

The principal objection to the use of mineral knobs is their liabilityto become loose upon or entirely detached from their neck, whichdiliculty arises from the manner of securing the knob to the neck, whichhas heretofore been done by means of cement, lead, or similar substancearound the neck in the cavity of the knob, depending entirely upon thestrength of such cement, 85e., holding in indentation made both in theneck and cavity ot' the knob. My invention is designed to overcome thisserious objection.

And to enable others skilled in the art to make my improvein ent, I willproceed to fully describe the same, as illustratedin the accompanyin gdrawings.

A is the knob. B the neck, which externally, as seen in Fig. I, aresimilar to ordinary knobs. I form the lower or inner part of the neckwith one or more projecting ears a a, or their equivalents. (See Figs. 2and 3.) Vithin the knob, at the proper distance from the outside, I forma channel, c, and cut as many grooves d from the outside down to thesaid channel as there are ears a on the neck; then iill or partiallytill the cavity in the knob with cement or any substance answering thesame purpose.; then set the ears of the neck into the grooves d, andpress down into the channel c, as seen in Fig. 2, turn the neckpartially around so that the ears shall set underthe solid part ot theknob, as in Fig. 2, and then leave the neck until the cement has becomehard. Th en the neck and knob cannot be separated without breaking' theknob.

My invention, though designed more particularly for door-knobs, isequally applicable to securing al] knobs which are first formedindependent of the neck. Therefore,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

Securing the neck to knobs, substantially as and for the purpose hereinset forth.

THOMAS KENNEDY.
